What is worth buying at Uniqlo?

I'm going to be in NYC for one more day and I'm going to stock up on some stuff. I rad over here that their underwears are pretty decent value. Which undershirts do you guys recommend? What about boxer briefs?

I also want to buy some long sleeve undershirts for winter. Any comments on their Heatech products?

Any comments about their premium down ultra light parka? It's relatively thin and it reminds me of the Patagonia jacket, but this one is $69.99! That's a pretty good value compared to Patagonia at $299.99.

If there are other stuff worth buying, please tell me and I'll take a look at it tomorrow morning.Edited by lsquare - 7/30/12 at 7:25pm

they have like 1000 different types of socks. They are all great, and cheap. I get 10 or so pairs every time I go.

i also like the dry v necks as basic tees. the premium cotton ones are super soft for undershirts.

i have never purchased anything at uniqlo that i have been bummed about later or felt was bad quality. I have gotten their raw denim, the vintage chinos, sweaters, sweatshirts, sweatpants, socks, underwear, tees, oxfords, etc. It's relatively good quality, or it's fine quality for the price, but either way i have never been like 'man that sucks that i got that $20 oxford" or whatever.
